Is it possible to beat a dogs nose and carry MJ without alerting those drug sniffing mutts? I didn't think so but then I saw these bags: basegear.com/op-sak-odor-proof-bag.html Anyone that watched Barry Coopers never get busted know that dog's can "smell through" alot. There was a bust he made where the gas tank of the car had been removed. The weed was sealed in PVC pipes, put into the gas tank, and the tank reattached and filled with gas. Coopers dog still smelled ganja "through" the gas tank, all the gas in it, and sealed PVC pipe. The guys were busted. But dogs can't smell through anything. The dog could smell the bud because smells permeate. When weed is put into a bag or container and sealed a dog can't smell what's inside the bag at first. But then the smells permeate through microscopic pores and soon enough the whole container including the outside smells like whats inside. But those bags I put the link to claim to be made of a non-permeable film and proven odor proof. If that is true a dog could have his faced pressed against the bag and not smell anything. I wish I could know for sure but I doubt there are any studies about how to odor proof your stash. So what do you think? Completely non-permeable and odor proof? Is it even possible to make 100% odor proof non-permeable containers? Would you trust your stash in these bags?
